两种钢渣源调理剂对水稻生长及氮磷钾吸收量的影响
Effects of Two Soil Amendments from Steel Slag on Rice Growth and Nitrogen, Phosphorus and Potassium Uptake
摘要
Abstract
A pot experiment was conducted to investigate the effects of two soil amendments(W and Y)derived from steel slag and their application rates (0.74, 1.47, 2.94, 5.88 g·kg-1 and 11.76 g·kg-1 for W;1.47, 2.94, 5.88, 11.76 g·kg-1 and 23.52 g·kg-1 for Y)on rice growth. The results showed that no significant change in rice yield was found following W amendments;conversely, a 20％ increase in rice yield was observed following Y amendments at rates of 11.76 g·kg-1 and 23.52 g·kg-1 as compared with NPK treatments. Y amendment at rates of 5.88～23.52 g·kg-1 increased straw mass by 24.02％～35.23％ when compared with NPK treatments. Combined application of Y amendments and NPK fertilizers increased subsequent N, P and K uptake by rice by 12.61％～21.55％, 7.63％～38.31％ and 11.89％～54.13％, respectively. The results indicated Y amendments could effectively accelerate subsequent rice growth at high application rates by increasing nutrient uptake in the soil studied(pH 6.51);Conversely, we observed no significant effects with W amendments.关键词
